other cases, and frequently in Irish specimens, the lacinize are much more narrow 
than those of |S. yu/monacea, and it ought to be referred to the var. /inearis. The 
_spermogones resemble those of S. pulmonacea, says TuLasnE. So far as regards 
their external characters, this statement does not at all agree with my own ob- 
servations. For, while those of S. pulmonacea, are generally minute and puncti- 
form, those of S. damecornis are generally largish and papilleform. The sper- 
matia and sterigmata are certainly the same in both; for they are the same, or 
at least similar, throughout the whole genus Sizcta. The ostiole is frequently large 
and round ; in the old state of the spermogone it may become an irregular, large 
stellate fissure, and the thallus may appear studded over with the pseudo-perfor- 
ations thus produced, precisely as in Parmelia saxatilis var. omphalodes. 
Rocks, Turk Waterfall, Killarney, Witson; in Herb. Hooker, Kew. (Sub 
nom. S. macrocarpa? var. syn. S. macrophylla, Tayl., in Macxay’s ‘ Flora 
Hibernica,’ p. 150.) This is certainly not a distinct species; and the specific 
name of the plant, S. damecornis, to which it belongs as a variety, ought to be 
restored to our Irish plant. The spermogones are papilleform. In some speci- 
mens the lobes are broad and rounded; but in others the segments of the thallus 
are much narrower, and resemble in their size and form those of S. pulmonacea. 
Specimen 4.—Var. macrophylla ; woods of Killarney; Tayutor, in Herb. 
Hooker, Kew. Taytorremarks on the label, “ I have seen specimens with seg- 
ments still narrower.” The colour of the thallus is deep-olive or brown. The 
papilleeform spermogones are with difficulty distinguishable; sometimes they are 
flattened, and have very pale-brown tips. In age they become large, with stellate- 
fissured ostioles. 
Specimen 5.—Var. macrophylla, Killarney Woods; Taytor, in Herb. Dr 
- Mackay, Dublin (author of the ‘“ Flora Hibernica”) ; with apothecia. In de- 
scribing the apothecia in the “ Flora Hibernica,” Taylor, apparently inadvertently, 
includes the spermogones, which he mistakes for young apothecia. The spermo- 
gones are large, brown-tipped papilla, resembling in form and size those of Rica- 
solia herbacea and R. glomulifera. ts spermogones should associate this plant 
with NyLanpeEr’s genus fcasolia ; but, in regard to cyphelle, it is a true Sticta. 
The spermogones are usually smooth and cone-like, with a round deep-brown 
ostiole ; but frequently also they are flattened, and their apex corrugated round 
a stellate-fissured ostiole. Their body is a kernel of dense white tissue, and 
which can be readily enucleated. The tissue becomes gelatinous under moisture. 
The spermogones are abundant, and are scattered over the whole surface of the 
thallus. The spermatia are about smth long, with a breadth of sath. The 
sterigmata are long and delicate, from ,;th to ;:th long, with a breadth of about 
anth, their articulations or component cells being distinct. 
Specimen 6.—Var. macrophylla, Java, Lops; in Herb. Hooker, Kew. This 
seems exactly the Irish plant. The spermogones are scattered chiefly about the
